IMPROVED DUMPlNG-CAR.

Spccilication forming part of Letters Patent No. 87,966, dated March 16, 1869.

l will enable those skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specification, in which drawing- Figure 1 represents a side elevation ot' this invention. Fig. 2 is a transverse section of the same.

Similar letters indicate corresponding parts.

This invention relates to a railroad or dump- A ing oar the box of which is supported on two pivots and steadied by side braces, which are secured to rock-shafts, from the ends of which extend catches acting on the swinging doors of the box in such a manner that when the side braces are turned down so as to retain the box in an upright position the swinging doors are locked by the catches; but if one of said braces is turned up the box is free to tilt, and at the same time the door on that side, being released, swings open and the contents of the box are dumped.

The pivots which support the box have their bearings in V-shaped slots, so that if the box is to be tilted to a steep angle the .pivots can pass from the corners of their V-shaped slots to the upper ends, and by these means the degree to which the box is tilted caribe accommodated to its contents.

A represents the box of my dumping-car, which is connected to the truckB by means of pivots a and slotted brackets b. The pivots a have their bearings in lugs or ears c, which are irmly secured to the bot-tom of the box, and the brackets b are bifurcated. so that they straddle the lugs, as shown in Fig. 1 of the drawing. The pivots a rest loosely in the slots of the brackets b, so that the box A can be tilted toward either side, and said box is retained in an upright posit-ion by braces d, which are secured to the inner ends of little rock-shafts e, that have their bearings in the longitudinal frame -tinibers of the box, as

shown in Fig. 2. W'hen both these braces are turned down the box is retained in an upright position, as shown in black outlines in Fig. 2; but if one of the braces is turned up the box ca-n be tilted, as shown in red outlines in Fig. 2.

The side pieces fof the box are hung upon rods g, which pass through suitable eyes or straps on their top edges, so that said side pieces form doors which swing freely in either direction; but when the box A is brought in an upright position and the braces d are turned down these swinging doors are locked by catches h, which are secured to the outer ends of/the rock-shafts e, and catch in suitable brackets t' attached to the doors. By securing the catches to the same rock-shafts on which the braces l are fastened I gain a decided advantage, since by turning up one of the braces the corresponding catch is simultaneously withdrawn from its door, and if the box is tilted said door swings open automatically.

lIhe braces d are operated by means of rods j, which extend to one end ot the car, so that either ot' the braces can be withdrawn and the b'ox tilted without endangering the person who operates the car.

The slots lc in the brackets b are V-shaped, as shown in Fig. 2, so that the degree to which the box A can be tilted can be varied.

1f the bearings or the pivots c were simply round holes, corresponding in position to the corners of the V-shaped slots, the box could only be tilted to a certain angle, (indicated by the line 1 2,) and if the box is lled with dry earth this angle would be sufficient to effect the dumping; but it' the box is lled with wet earth or marshy ground, the box must be tilted to a steeper angle in order to effect the dumping. In this case, instead of allowing the pivots (t to rest in the corners of the V- shaped slots, I cause them to slide up to the top ends of their slots, and the box assumes the position shown in red outlines in Fig. 2. This dumping-car is of particular advantage for the portable railroad on which Letters Patent have been granted to me, as assignee of John N. Peteler, September 23, 1866; but said ear can also be used in any other operation Where dumping-ears are required.

2. The V-shaped slots kin the brackets b, which form the bearings for the pivots a of Having thus described my invention, what I the box A, as shown and described.

claim as new, and desire to secure by Letters Patent, is

l. The combination of the braces d and catches h with the rook -shafts e, swinging doors f, and box A, hung on pivots a, substantially in the manner set forth.
